Description

Patient's recognition methods of X-ray film user interface

The cross reference of related application

The application number that the application requires on September 4th, 2002 to submit to is No.60/408,079, and title is the U.S. Provisional Application No. of " Patient identification method for CAD user-interfaces ".

Technical field

The present invention relates to X-ray film identification field, more specifically, relate to discriminating digit X-ray film in computer user interface.

Background technology

X-ray film can scan by film digitizer (film digitizer), and converts number format to.Subsequently, digitized film is stored, so that utilize image analysis algorithm, CAD (Computer Aided Detection: computer-aided detection), further retrieve or analyze for example.Film digitizer can obtain from companies such as for example Canon, Howtek, Kodak or Vidar.Film digitizer links to each other with standard computer, and is stored as image by Standard User Interface Control scanning, identification and with digitized film on disk.The Standard User interface (comprising quality control, error detection and error correction) that is used for digital switching device control can obtain from Vider, Applicar or Merge.

In diagnostic procedure, need carry out fast film, discern reliably, to increase treatment effeciency and to reduce with mistake and discern the relevant risk of makeing mistakes.In addition, also to analyze the digitlization X-ray film through application software (for example CAD) commonly used, and with CAD result and respective digital X-ray film carry out reliable related be very important.

In the ordinary course of things, the breast X-ray film (mammogram) on common interpretation alternator of radiologist (alternator) or the light box (light box).The radiologist notices suspicious place, and it is recorded in the medical report.Yet the radiologist is general unavoidable can to miss the certain cancers film.In order to reduce error rate, can be by second this X-ray film of radiologist's interpretation, and two doctors' result compared.

CAD result can be used for serving as second radiologist to a great extent.(be also referred to as " utilizing CAD to carry out the secondary interpretation ") in one case, at first, the radiologist is by computer, the interpretation X-ray film.In case the radiologist notices suspicious discovery, she can check the suspicious region of being analyzed identification by CAD, for example as on the monitor or cover profile (overlay) on the breast X-ray film of digitized version on the paper that prints.This suspicious region susceptible of proof radiologist's discovery perhaps can point out the radiologist to check that once more she does not find zone suspicious, that but highlighted by computer.

(be also referred to as " by the indicative interpretation of CAD ") in another case, the radiologist is interpretation X-ray film and check CAD result simultaneously, and with the changing of the relative positions before and after between them, she carries out interpretation to utilize CAD result's " prompting ".

In either case, it is important to guarantee that CAD result is correctly related with X-ray film, with the correct identification of guaranteeing the result and avoid film and CAD result's confusion.At present, commercially produced product uses big metering method to realize above-mentioned situation.

For example, use bar code system.When film was carried out digitized processing, the approximately equalised separator page of size and film also scanned.This separator page is as the separator between the film of the film of a case and next case.On separator page, print bar code.Digitization system reads this bar code, and to carry out numeral related with image.The operator need not import patient's name, registration number or other identifier, and this bar code information promptly is used as the identifier of case.Only by discerning the patient with bar code value corresponding identifier (number).After the digitized processing, film is put back in the sheath together with the separator page that has bar code.

When film is hung on the alternator, use the bar code on the bar-code reading device scan separation page or leaf.Alternator comprises carries out related computer and logical circuit with CAD result with specific alternator position (position of corresponding X-ray film).Like this, according to the position of alternator, on the miniscope in being integrated in alternator, show correct digitized image and CAD result.Corresponding value identifiers with bar code (together with alternator position) identification patient.

When radiologist and other healthcare givers use patient's name and patient's record identifier to discern the patient and during with cross-correlation (cross correlation) such as patient and other medical information, report, requirements, this method is then perfect inadequately.Because can only be by bar-code identification and the value identifiers that is associated with it identification CAD result, patient's name or record and CAD result related relates to a kind of method of indirect and insecure cross reference, promptly from CAD result to bar code, arrive address name again.This method is not only inconvenient, time-consuming, and makes mistakes easily.

In another system, on each film, paste bar code paster (paster comprises the directed information of each film).Digitalizer uses this bar code, and it is associated with patient's film.When checking film, read bar code paster on the film with bar-code reading device, and show that on monitor suitable image is together with CAD result.In this system, CAD result is not associated with the position of alternator.This method is perfect equally inadequately: only utilize CAD result's bar code numbers and be attached to the relation mechanism of the cross-correlation of the bar-code label on the X-ray film as CAD result and patient name.

United States Patent (USP) 5,748,173 " Hybrid display simultaneous side-by-sidereview of radiographs " (" being used for checking side by side simultaneously the mixed display of radiograph ") have described another method.In described system, utilize bar code scanner or CCD camera, from being placed on the film on the inspection box (alternator or lamp box), directly obtain the patient information of name or patient's number form.But this method also has deficiency, before the method call CAD result who utilizes the application to describe, must discern CAD result by other means with patient's name or number earlier.

Use other strategy identification X-ray film in addition.For example, the operator can import user's name and identifying information.Subsequently, it is related address name and digitized image to be carried out numeral.When checking case, the radiologist imports user's name in computer, can show suitable image and CAD result.In addition, the radiologist can select the patient's name from a tabulation.The shortcoming of this method is when digitized processing, must manually import address name, and may also will import once more when check.

Summary of the invention

According to one aspect of the present invention, a kind of method is provided, by this method, can from the digitized X-ray film, obtain the patient information that Gong the people on the label reads automatically.Subsequently, use this readable patient information to discern corresponding X-ray film.According to another aspect of the present invention, the label of digital extraction digitized X-ray film, and carry out relatedly with corresponding film, and show, so that allow the user read.The advantage of this method is, needing can avoid with indirect method (for example, be attached to the bar code on the film or must import patient's name or identification number by scanning) identification film, and overcome some defectives of prior art thus.

In one embodiment of the invention, the label of digital extraction can strengthen by increasing contrast or removing grain background, is included in alphanumeric information in the label to make things convenient for user's interpretation.

Digitized label also can be carried out related with the result of X-ray film graphical analysis (for example CAD analyzes).The readable label of people can be used in the user interface relevant with CAD, this user interface includes, but is not limited to quality, the beam worker tabulation of control figure X-ray film, to utilize CAD to check X-ray film, to select CAD result, so that check X-ray film, in the checking process of X-ray film or after checking, show CAD result and form the CAD destination file with electronic form.

Among another embodiment, digitized label can be used for the digitized X-ray film that belongs to same patient is divided into groups automatically.Its implementation is: by using image comparison techniques and using predetermined relevant criterion that these films are carried out association, come the label of different films is carried out numeral relatively.

Among the another embodiment, can be from label the digital extraction subtab, and carry out related with corresponding X-ray film image and/or graphical analysis result (for example CAD result) subtab.By using information selected from label, can recognition image, this method has strengthened the flexibility of the retrieval film of wanting.

The detailed description of preferred forms

Each X-ray film (bum) is gone into to the user profile of film to have made mark by " burning ".This can realize that this alphanumeric information is generally listed patient's name, date of birth, identification card number, registration number or technical staff's name or identifier by a kind of device of alphanumeric information exposure zonule film (about 1 * 2 inch) that utilizes on film.

Depend on medical institutions and equipment, patient information areas can perhaps can change at the same position of all films.Patient information areas can be at the edge of film, perhaps certain position of the background area beyond the anatomical features shown in the film.Patient information areas can be black matrix wrongly written or mispronounced character or white gravoply, with black engraved characters, can be print or computer generate and also different and different with medical institutions, imaging device and each time inspection of visual field (fields) and their arrangement.

An aspect of of the present present invention, user profile zone (being label) can be used to replace other numeric identifier, as patient's numeric identifier.Thereby, a kind of method and system of discriminating digit X-ray film is provided, comprise on this film having the alphanumeric information relevant and the label of out of Memory that for example, out of Memory can be the conditions of exposure of (but being not limited to) film with the patient.

With reference to figure 1, from X-ray film 10, obtain the digitized image of label 11, and in look-up table (look-up table) 12, to carry out numeral related with the corresponding digital X-ray film.Go up demonstration digitized label 14 in user interface 16 (for example computer screen), utilize the alphanumeric information on the label to discern corresponding film to allow the user.Label image can show separately, perhaps shows simultaneously with the X-ray film image.

In some cases, the label of digital extraction may have grain background, fuzzy or contrast may be big inadequately, makes user's sense information easily.In these cases, label can carry out the numeral enhancing.For example, strengthen by label, meaning will be carried out certain step, to remove grain background, to strengthen contrast and enlarged image between alphanumeric notation and the background.These steps are well known in the art.Thereby as shown in Figure 2, label 14 can be enhanced to and strengthen label (EL) 20, and in look-up table 22 (look-up table) with corresponding X-ray film or with corresponding label (not strengthening label) or digital related with the two.Should be understood that if the EL label corresponding with it is associated, then EL can be associated with the corresponding digital X-ray film indirectly.

Image analysis algorithm (for example CAD algorithm) can be applicable to digitized film, and result can be associated with label (or EL) and corresponding X-ray film image (Fig. 3).Patient information areas (label or EL) is as unique identifier of patient, image and graphical analysis result.Thereby label can show simultaneously with X-ray film image and CAD result, perhaps, can only together show with the graphical analysis result.

In one preferred embodiment,, obtain digitized label from the remainder (remainder) of digitized X-ray film by automatic location and digital extraction.In order to realize above-mentioned effect, can use pattern recognition well known in the art (pattern recognition) and image processing method.These methods can include, but is not limited to rim detection and Texture Segmentation.For example, in rim detection, determine the gradient of the pixel intensity of image, and discern its gradient and the corresponding image section of predetermined gradient, promptly relevant feature with the existence of this label with it.The digital label that extracts will be used to discern the image of certain case.

According to another aspect of the present invention, but provide the user interface of a kind of interactive identification patient information areas position, and subsequently digital extraction is carried out in this zone to the user.

According to another aspect of the present invention, the normal place that will be in the patient information areas of the directed film of difference is stored on the computer disk.According to the orientation of film, can search the normal place of patient information areas on the film, and from this extracted region patient information areas.

The extraction that should be noted that patient information is corresponding to chooser image in the digitized X-ray image, but needn't the actual remainder (the additional part of subimage) of removing image.As those skilled in the known, the extraction of subimage can copy in the new frame buffer by the pixel with subimage, and with subimage save as one independently image realize; Perhaps pass through in original image, to determine a rectangular area, and express a new subimage with the form of the coordinate of rectangular area in reference original image and the original image and realize.The actual expression of zone that is extracted and subimage is determined by software architecture and concrete enforcement purpose of the present invention to a great extent.

In these cases, and with reference to figure 4, label 14 (or EL) can be subdivided into one or more subtabs 40.As above-mentioned label, can carry out digital extraction to subtab, and in look-up table 42, carry out related with corresponding label, digitized X-ray film and/or graphical analysis result.Because from label, can extract more than one subtab, different subtabs can corresponding X-ray film image 44 or graphical analysis result's same label.Subtab (for example can comprise in address name, the exposure process employed voltage or directed information, in-tiltedly-side (MLO) or skull-tail side (CC)), and to which side imaging (left side or right side) of chest or be included in out of Memory in the label.Subimage also can comprise the combination of above-mentioned information.The segmentation of label helps allowing the user to call one or more images again on the basis of patient's Proprietary Information (for example address name) out of Memory in addition.

According to the common pending application US10/205 of the application's reference and combination, the method described in 599 can detect application with a kind of label and be assigned to digitized image.This method comprises such step: obtain the model from a plurality of of at least one attribute based on digital label, select label to obtain model; And utilize selected label to obtain model, and detect the application from a plurality of labels, select label to detect and use.

In certain embodiments, the selection of obtaining model can comprise such step: obtain at least one attribute of digital label, and carry out search, obtain model with the Attribute Recognition that utilization is obtained.Label detects to be used and can select like this: according to the relevant information of selecting that model obtains digital label of obtaining, and carry out search, come identification label to detect application to utilize this to obtain information at least.

The application with reference to and the common pending application US10/205 of combination, also describe an example in 599 and support label to detect the system that uses appointment.This system comprises a case input system.This case input unit is used for from a plurality of models that obtain based at least one attribute of digital label, selects label to obtain model; And utilize selected label to obtain model, and detecting the application from a plurality of labels, selection marker detects to be used.

This system also can comprise arithmetic server, detects in order to retrieval and with selected label to be used for digital label.

Should be understood that also can use other method that label is detected to use is assigned to the digitized X-ray film.For example, this application can be a kind of default application.

In diagnosis algorithm, for example, projection (screening) breast X-ray film, information much at one is used on all films of same patient, although in many cases, the information (for example, X-ray electric current and orientation) that belongs to each indivedual film is also shown on the label.Thereby label is variant aspect trickle at some.

Thus, although may be exposed, the influence of the variation of noise and other human factor, all films of same patient all comprise the closely similar zone of about 1 * 2 inch content.Thereby the patient's label that extracts from an image of a case can be used to represent all images of this case or this patient's all images.Therefore, the inventive method on the other hand, the digitized alphanumeric information of available label will belong to a patient's image packets.In order to divide into groups, on film digitizer, load some patients' film, and with film scanning and change into digital form.Do not use separator page, and some patients' film can be mixed.Patient information areas on each film is discerned automatically, and with other film on corresponding information carry out relevant treatment.The film that patient information areas has high correlation belongs to same patient to thinking, the film of low correlation is to then belonging to different patients.In addition, can discern at the enterprising line character of identified areas, and directly obtain patient's name and out of Memory with alphanumeric format.Like this, can obtain the patient's name and also be used as the identifier of film, thereby can divide into groups to each patient's film according to the patient's name.

By comparing the patient information areas (label) of two films, can determine two similitudes between the film.Well known to a person skilled in the art that correlation technique can be used for determining similitude, this correlation technique includes, but is not limited to displacement/rotation and intensity/contrast variations.Predetermined high correlation represents that two films belong to same patient, and predetermined low correlation represents that two films belong to different patients.

Usually, continuous patient's film is put into the input pallet of film digitizer.A patient's film is divided into one group, then is film of next bit patient etc.Thereby, correlation technique will only be used for continuous film to.In most of the cases, 4 films that have high correlation and belong to same patient are one group.Correlation between first film of a patient's last film and next bit patient is very poor.Then, four films of next bit patient have high correlation mutually, therefore, can the film that belong to same patient be divided into groups.

As another kind of mode, also can be not with each patient's film grouping and scanning multidigit patient's film.In this case, be preferably in each all films between carry out relevant treatment.

The digitized label of each film in a group can with arbitrarily or all digitized films that belong to this group to carry out numeral related.Thereby, can show one group of all interior digitized film by only selecting a label.Should be understood that and have other demonstration combination (2 films of 1 label, 3 films of 1 label, 4 films of 1 label etc.) arbitrarily in one group.

This method is not limited to the grouping of 4 films of every patient.Utilize correlation technique can handle and discern the film of every patient's any amount.

Use method of the present invention, can from a plurality of memory images, select and retrieve 1 X-ray film image.Now,, can on user interface, show and the corresponding label of store films (or EL or subtab) of all or predetermined quantity, select one or more desired X-ray films to allow the user with reference to figure 5.Should be understood that according to present embodiment, but retrieving images analysis result (for example CAD analysis result) also.For example, can on computer monitor,, show all retrievable patients' label (or EL or subtab) with tabular form.Digital patient's identifier (that is, label) in the tabulation that the technical staff shows on the user interface by operation generates CAD result's the worksheet order of X-ray film on alternator or the light box (for example, corresponding to).For example, this tabulation can be the scroll list, and can utilize " cut and paste " in the tabulation to change order.Perhaps, use two tabulations, one is used for whole existing patients, and one as worksheet.For example, the technical staff can utilize mouse or touch-screen user interface, by desired order numeric identifier is moved on to another tabulation from a tabulation.Display label can also allow the user directly select one or several desired patients' name in tabulation, and does not need patient's name and id number cross-reference, perhaps the bar code on the scan film.

Fig. 6 has shown some possible execution modes of label/film display that label wherein can show simultaneously with digitized film and/or graphical analysis result.Configurations shown/the compound mode that should be understood that other also is possible.

In addition, can use digital label with case with a certain sequence arrangement, for example, set up the orderly patient worklist that will consult by the radiologist, just as patient's film is hung on the alternator.

Equally, can utilize digital label that case is arranged in bivariate table, this is corresponding to case is arranged on the light box.

In the interpretation process, CAD result is presented near alternator or the inspection box the monitor.In general workflow, after the radiologist has analyzed image, show CAD result's (for secondary interpretation situation), to obtain prompting to other suspicious region.After checking film, the radiologist selects corresponding patient information areas (for example, with mouse or touch-screen) on monitor.Then, corresponding image and CAD result show on same display.Because image is related with the patient information areas numeral with CAD result, this can realize.

No matter digital map similarly is to be presented at when still being printed on the medium on the monitor, all can use the label of digital extraction.In addition, arrange (tabularalignment), color-code or suchlike other method by using figure, form, carry out related with the digital extraction label digitized image by the eyes observation, the user can confirm whether label is really relevant with its associated images, and can discern the image that belongs to particular patient thus.

The recognition methods that should be understood that above-mentioned patient's x-ray image can be used on the digitlization work station, made digitized processing there after, image is shown, so that control of quality; Or being used in CAD as a result on the display workstation, the radiologist can use this display workstation to check that CAD thinks the zone of suspected diseases.
